Best practices for Backup Exec 2014 Agent for Microsoft Hyper-V

Best practices include tips and recommendations to help you effectively use the Backup Exec 2014 Agent for Microsoft Hyper-V. For more information about the Agent for Microsoft Hyper-V, see the Backup Exec 2014 Administrator's Guide.

General recommendations for using the Agent for Hyper-V

  • Perform a periodic full backup.

  • Back up to a disk-based storage device instead of to a tape device.

  • Ensure that each virtual machine has a unique name. If you have two virtual machines with the same display name, backup jobs may fail.

  • Ensure that the correct version of the Hyper-V Integration Components is installed. The version of the Hyper-V Integration Components should match the version of Hyper-V that you use. Note that Hyper-V Integration Components cannot be disabled.

Best practices for using Granular Recovery Technology (GRT) with the Agent for Hyper-V

  • To use GRT, install the Agent for Windows on the virtual machine on which data is to be restored.

  • Do not use GRT for system file restore for disaster recovery of a virtual machine. Instead, restore the full virtual machine.

  • If you want to use GRT for some virtual machines, but not for others, set up jobs as follows:

    • For virtual machines that do not require GRT, create a backup job with all GRT options disabled.

    • For virtual machines that require GRT, create one of the following jobs:

      • For virtual machines that require file/folder GRT, but do not have SQL, Exchange, Active Directory, or SharePoint installed, create a backup job and select the option Use Backup Exec Granular Recovery Technology (GRT) to enable the restore of individual files and folders from virtual machines.

      • For virtual machines that require GRT for SQL, Exchange, Active Directory, or SharePoint, create a backup job and select the appropriate application GRT checkboxes. For example, to use GRT for Exchange, select the option Enable GRT for Microsoft Exchange databases and mailbox items on virtual machines. File/folder GRT can also be enabled in this job if you also require file/folder GRT. The Agent for Windows must be installed on the virtual machines that you include in this backup job. You must provide the appropriate credentials to access the virtual machines and the applications that reside on them.

    • For virtual machines that do not support GRT, such as Linux and Mac, create a separate backup job and deselect the four options to Enable GRT for <Microsoft application name> on virtual machines. If a virtual machine does not support GRT, but the options to enable application GRT are selected, the job will complete with exceptions.

    Note:

    Do not include the same virtual machine in multiple backup jobs. If Agent-based backups are also being performed, schedule them so that they do not overlap with the GRT-enabled backups of the virtual machines.

  • If you have Microsoft SQL installed on a virtual machine, you can select the option Run a SQL Log backup after backing up the virtual machine to back up the SQL logs for the databases that use logging. After the logs are backed up, the data from the logs is committed to the database and the log is emptied in order to receive more data. If you do not select the option to perform SQL log backups, the SQL logs continue to grow until the disk is full or until you perform a manual backup job to back up the logs. The option to run a SQL log backup is located on the Virtual Machines dialog box.

  • To use GRT for individual items from Microsoft Active Directory, Exchange, SharePoint, or SQL, do the following:

    • Install the Agent for Windows on the guest virtual machine.

    • Ensure that you have a valid license for each application that you want to protect.

    • Ensure that the credentials for the guest virtual machine are valid for the application that you want to protect.

    • Use the same requirements for backing up Microsoft Exchange on a physical computer when you back up Exchange on a virtual machine.
